ASP.NET MVC 4 Routes - controller/id vs controller/action/id
提问by Arman Bimatov
I'm trying to add a route to the default one, so that I have both urls working:
我正在尝试将路由添加到默认路由，以便我的两个 url 都可以工作：
http://www.mywebsite.com/users/createhttp://www.mywebsite.com/users/1
http://www.mywebsite.com/users/createhttp://www.mywebsite.com/users/1
This will make the first route work:
这将使第一条路线工作：
routes.MapRoute(
name: "Default",
url: "{controller}/{action}/{id}",
defaults: new { controller = "users", action = "Index", id = UrlParameter.Optional }
);
However, the second route won't work obviously.
但是，第二条路线显然不起作用。
This will make the second route work, but will break the first one:
这将使第二条路线工作，但会破坏第一条路线：
routes.MapRoute(
name: "Book",
url: "books/{id}",
defaults: new { controller = "users", action = "Details" }
);
How to combine the two route configurations so that both URLs work? I apologize if there is already a question like this on SO, I wasn't able to find anything.
如何组合两个路由配置，使两个 URL 都能工作？如果在 SO 上已经有这样的问题，我深表歉意，我找不到任何东西。

The key is to put more specific routes first. So put the "Book" route first. EditI guess you also need a constraint to only allow numbers to match the "id" part of this route. End edit
关键是把更具体的路线放在第一位。所以把“Book”路线放在第一位。 编辑我猜你还需要一个约束来只允许数字匹配这条路线的“id”部分。结束编辑
routes.MapRoute(
name: "Book",
url: "books/{id}",
defaults: new { controller = "users", action = "Details" },
constraints: new { id = @"\d+" }
);
routes.MapRoute(
name: "Default",
url: "{controller}/{action}/{id}",
defaults: new { controller = "users", action = "Index", id = UrlParameter.Optional }
);
And ensure that the "id" parameter in your "Details" action is an int:
并确保“详细信息”操作中的“id”参数是一个整数：
// "users" controller
public ActionResult books(int id)
{
// ...
}
This way, the "Books" route will not catch a URL like /users/create(since the second parameter is reqiured to be a number), and so will fall through to the next ("Default") route.
这样，“Books”路由将不会捕获类似的 URL /users/create（因为第二个参数需要为数字），因此将落入下一个（“默认”）路由。
